CHOPPINGI-KNIFE.

SPECIFICATION forming part of Letters Patent No. 554,788, dated February 18, 1896. Application filed August 30,1895. Serial No. 561,027. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE G. NEWELL, a citizen of the United States, residing at Clearwater, in the county of Wright and State of Minnesota, have invented a new and useful Chopping-Knife, of which the following is a specification.

My invention relates to chopping-knives, and more particularly to those operated by hand for ordinary culinary purposes and for cutting seed-potatoes; and it has for its object to provide a device cheap in manufacture, simple in construction, light, and easily cleaned, with no places for foul matter to lodge, not liable to clog in use, and which shall be rapid in execution.

WVith these and other objects in View my invention consists in the various details and combination of parts, an as herein set forth, and more particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of the chopping-knife. Fig. 2 is a vertical transverse section thereof. Fig. 3 is a detail view of the handle part, and Fig. l is a detail view of the central blade and one of the transverse blades.

Referring now to the drawings, 1 designates the central longitudinal cutting-blade, sharpened and curved at its lower edge, and extending upwardly, as at 2, to receive the handle 3. This blade 1 is provided with slits 4, extending downward from the top more than midway the width of the blade, and each slit being adapted to receive another and a trans verse cutting-blade 5, which is likewise slitted at 6, but from its lower edge, the slit in the transverse blade being of such an extent that when the cutting-edges of the blades are even the inner ends of said slits 4 and 6 will abut one against the other. These slits correspond to the thickness of the metal used, so as to make a neat closed joint when the parts are assembled. There are a plurality of slits 4:, corresponding to the number of transverse blades employed, which in the present case is four; but any desired number maybe employed.

The handle 3 is provided integrally therewith with upwardly and outwardly bent deflectors 7. Between the deflectors and the hollow handle the metal is bent on either side, forming wings 8, so as to lie flatly and firmly against the upper extended portion of the central blade, and extending downwardly thereover sufficiently to give rigidity and strength to the assembled parts. Each transverse blade 5 is provided at its upper end with a slot 9 to receive the lower edges of the respective deflectors. These deflectors are bent sharply back against the downwardly-extending wings 8, and at the line where said deflectors begin to curve away from said wings 8 I make slots 10 in the deflectors to receive the tongues 12 of the respective transverse blades 5. All of the blades are preferably tapered from the wider bottom end and are curved at their lower cutting-edge to correspond to the curvature of the chopping-bowl. The slitset are preferably not parallel, but are slightly farther apart at their upper ends than at their lower ends, this divergence causing matter forced between them toward the handle to freely loosen as it is forced upward, although said slits may be made parallel.

The interlocked arrangement of the blades and the deflectors produces a rigid bracing which gives durability and strength and allows the use of thinner and hence more easily sharpened and lighter material, while the fact that the slits 6 are relatively shallow and that the lower ends of slits 4 extend approximately near to the cutting-edge insures rigidity from bending and twisting of the blades relatively to each other.

The parts are assembled by inserting the transverse blades 5 in the blade 1, the slits 6 fitting over the lower portion of the latter. Then the handle is adjusted with the lower edges .of the deflectors occupying slots 9 and the tongues 12, resting in slots 10, the whole being fastened together by two rivets, one preferably at either end and near the top of wings 8.

It results from my effective trussing and bracing arrangement,as described above, that 'the shock from the downward thrust of the knife in use is received primarily and directly by the handle or handle-wings, and this is the case whether one or all the edges take the blow. The transverse blades are held from lateral twisting, and the whole structure is made to resist the strain incident to the use of such an implement.

It is obvious that many changes in form and proportions may be made within the limits of my invention and that its use is not limited to a hand device.

\Vhat I claim is 1. The combination of a central cuttingblade, transverse cutting-blades, the upward ly-diverging deflectors located at opposite sides of the central cutting-blade and interlocked with the upper ends of the transverse blades, and a handle located above the deflectors, substantially as described.

2. The combination of a central cuttingblade provided with a plurality of slits, and a plurality of transverse blades and interlocked with the central blade and extending from opposite sides thereof, said transverse blades diverging upwardly, whereby the device is self clearing, substantially as described.

The combination of a central cuttingblade provided with slits extending from the top near to the cutting-edge thereof, with transverse blades, each provided with a shallow slit medially thereof extending from the cutting-edge and also provided with a shallow slot at its upper end, and a combined handle, stiii'ening wings and deflectors all struck out of one piece of metal, said deflectors each bent up sharply against the depending wings and curved outwardly and provided with lateral slots to receive the upper ends of the transverse blades, the whole suitably riveted through the said Win gs and central blade, substantially as described.

4. The combination of a central cuttingblade, with separate blades secured to the central blade, and a combined handle, stilfening wings and deflectors struck out of one piece of metal, said deflectors each bent up sharply against the depending wings and curved outwardly and provided with lateral slots to receive the upper ends of the transverse blades, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
